i'm not endorsing this company as i don't really know much about them, but the dyno results he posts should give you a lot to think about. even if you don't use his service/product, his dyno results show how airbox/exhaust improvements will increase your performance.

If I'm reading everything right what that dyno graph shows is not just from exhaust and an airbox. It also includes an ECU and Power Commander. It has been reprogrammed for ignition timing and fuel delivery.

(Taken directly from the webpage....) Remember that these are only full throttle tests and do not reflect any driveability improvements
To quote the guys on British TopGear ".... POWER!!!!!!!!!! ...."

Probably close to $2 grand to get 10 HP? Wow.....definitely not cheap horsepower.... but nice to know it's there if you have a fat wallet.

closer to $1K if you just have modest upgrades. but look at how much people spend on pipes and air intake anyways. that's most of the budget there. and 10HP might not sound like a lot out of context, but for this bike it's a 20% increase in power which is pretty significant. and at 6250 RPMs, where you'll spend a lot of time when you have the throttle open, it's a 15HP increase, or 30% more power over stock. how much would you spend for a 30% more power? i look at this particular mod as a supplement to those that have already upgraded the bike with pipes/intake/FMS. but either way, most bike owners spend hundreds or thousands of dollars upgrading their rides in various ways, so it would make sense that some of that was spent here.

Just came back from Ivan's. It was a nice ride from where I'm at, like 28 mins. He did the flash in like 10 mins. I removed the ecu for him and he went to work.
Overall the bike feels great now. I had a Vance&Hines naked intake and a cobra slip on. The backfires and burbles were cool but annoying after a while. This time smoothed that out and feels much better when taking off or reapplying throttle. Haven't pushed it yet since I just got the bike, to hell with a warranty lol. Not a bad shop, I was the 2nd person there and the first one out.
I will go back later for the fuel controller. He suggested it but said I didn't really need it, that I should be good for now.
